Description
Technical field
The utility model belongs to the electric power network device, specifically is a kind of intelligent reactive power automatic compensation controller.
Background technology
Reactive power compensation device is a kind ofly can stablize line voltage, improve the electrical network three-phase imbalance, saves energy, raising transformer increase-volume utilance, satisfy the increase-volume demand, eliminates electromagnetic pollution and improves the device of Electrical Safety reliability.
The reactive power compensating controller of prior art mainly contains two types, and a kind of is the static reactive power compensating controller, and another kind is the dynamic reactive power compensating controller.The static reactive power compensating controller mainly adopts electromagnetic AC contactor, owing to produce bigger shoving and overvoltage in the capacitor switching process, can cause the contact sintering and the electric capacity of contactor to puncture, contactor itself and life of capacitors are shorter, be not suitable for frequent operation, but it is low in energy consumption that it has when through-flow, safeguards and the little advantage of replacement cost, the relatively more suitable little occasion of load fluctuation.The dynamic reactive power compensating controller mainly adopts combination switch, it is that contact with withstand voltage big controlled current silicon and magnetic latching relay is in parallel for a combination switch, pass through microcomputerized control, automatically seek best point and the best excision point of dropping into, realize the excision of voltage zero-cross input and current over-zero, break-make moment is finished by controllable silicon, move through-flowly to make the contact adhesive and finish through the pulse voltage triggered by magnetic latching relay, low-power consumption, do not generate heat, no harmonic wave, the scope of application be big, safe and reliable.But it has the big problem of production cost height, maintenance and renewal cost.
Summary of the invention
The purpose of this utility model is to overcome the defective that exists in the prior art, a kind of intelligent reactive power automatic compensation controller is provided, it has merged the advantage of static reactive power compensating controller and dynamic reactive power compensating controller, eliminate the compensation dead angle of traditional static reactive power compensating controller and dynamic reactive power compensating controller, more flexible and changeable compensates user's reactive power is multi-faceted, improves the power grid quality that the user uses.
The purpose of this utility model is achieved in that a kind of intelligent reactive power automatic compensation controller, and it comprises microcontroller circuit, signal acquisition circuit, power circuit, dynamics compensation circuits, static compensation circuit; A/D change-over circuit and signal resolution module that described microcontroller circuit comprises microprocessor, is connected with microprocessor; Described signal acquisition circuit comprises current sampling circuit and the voltage sample circuit that is connected with the A/D change-over circuit; Described power circuit comprises DC12V power module, AC220V power module and isolates immunity module; Described dynamics compensation circuits comprises that this power amplification circuit connects combination switch and capacitor successively by the signal resolution module driving, by the power amplification circuit of DC12V power module power supply; Described static compensation circuit comprises that by the power amplification circuit that signal resolution module drives, the DC12V power module is powered, this power amplification circuit connects solid-state relay drive circuit, A.C. contactor and the capacitor by the power supply of AC220V power module successively.
Described microprocessor is the microprocessor of 16 bit.
The utlity model has following advantage: controller is core with the microprocessor, record the phase difference of load current, line voltage and electric current, voltage by voltage, current sampling circuit and A/D change-over circuit, by calculating power factor and needing the reactive power of compensation.Judge, make a strategic decision according to capacity, line voltage and the anti-time limit characteristic of every group capacitor then, the output control signal select to start dynamics compensation circuits or static compensation circuit, through power amplification circuit, and the putting into operation or move back fortune of control capacitor group.The innovative point of this controller mainly is: 1. by high strength isolation, immunity module, heavy-current control and light current control sets are combined in the controller of miniaturization, have made things convenient for the complicated electric power control of factory to install and use.2. by bit microprocessor and signal resolution module, judge that effectively load is frequent fluctuation or non-frequent fluctuation, thereby still be the A.C. contactor switching according to load character instruction combination switch switching.3. switching device is maximized favourable factors and minimized unfavourable ones. by the mixing switching compensation of combination switch and A.C. contactor, further strengthened purpose energy-conservation, consumption reduction.4. switching device cost performance height, the scope of application is wide.
